Title: Method for removing residual molten iron from tilting type skimmer
Inventor: NIKO KIYOSUKE
IPC: C21B7/14
Filed: 1990-09-28
Abstract: PURPOSE:To improve working efficiency for removing residual molten iron by controlling the tilting velocity of a skimmer so as to discharge only molten slag while measuring the residual molten iron level in a skimmer and quickly discharging the residual molten iron in the skimmer. CONSTITUTION:The skimmer 1 is loaded on a carrier 12 as adjustable to the tilting velocity with a tilting driving device 15. At the time of tilting the skimmer 1 frontward, bottom faces 6a, 6b of slag discharging holes 6 in side walls of a molten iron receiving part 2 are formed to a cross sectional shape having notching part at side apart from the residual molten iron side. At the time of removing the residual molten iron by tilting the skimmer 1 frontward, the tilting velocity of skimmer 1 is controlled with the tilting driving device 15 so as to discharge only the molten slag without overflowing the molten iron from the slag discharging holes 6 while measuring the residual molten iron level in the skimmer 1 with a level sensor 19, and the residual molten metal in the skimmer 1 is discharged from a molten iron flow-out hole 3 while quickly passing through a molten iron under-stream hole 5. By this method, after replacing the skimmer, a molten iron tapping work is immediately executed.

Title: Optical disk
Inventor: SUZUKI HIROYUKI
IPC: G11B7/24
Filed: 1993-09-21
Abstract: PURPOSE:To improve the corrosion resistance of the optical disk by forming a protective film in an outer peripheral part so as to wrap the film up to the rear surface of a substrate. CONSTITUTION:The magneto-optical disk is produced by the following procedures: Thin-film layers 2 consisting of a transparent film 4 for optical interference, a perpendicularly magnetized film 5 and a metallic reflection film 6 are formed on the substrate 1 made of a resin. Since an outer peripheral mask is not used at this time, the thin-film layers 2 infiltrate to the outer peripheral flank 8 of the substrate 1. After a silicone resin is applied on the substrate 1, the substrate is rested at room temp. to cure the resin and to form the protective film 3. The protective film 3 infiltrates to the rear surface of the substrate 1 in the outer peripheral part at this time. Changes in defect rate of the magneto-optical disk produced in such a manner and the conventional magnetooptical disk are investigated by spending about 1000 hours in environmental tests at 80 deg.C and 90%RH. The results, then, reveal that while the defect rate of the latter increases to 26.2 times, the defect rate of the former is 1.2 times and hardly increases and that the former is greatly improved in corrosion resistance as compared with the latter.

Filed: 1998-09-11
Abstract: PROBLEM TO BE SOLVED: To realize an oscillation circuit for outputting an oscillation signal with stable frequencies under any temperature by following-up temperature change. SOLUTION: A signal corresponding to the voltage level of the output signal of a comparator 10 is fed back through a resistance element 40 to one input terminal of the comparator 10.
